Specification of Letters Patent.

Patented Sept. 16, 1913.

Application filed January 19, 1912. Serial N 0. 672,125.

To all whom/it may concern I so ' Be it known that I, URIAHROBERTS, acitizen of the United States, and resident of Columbus, in the county ofColumbia and State of Wisconsin, have invented new and usefulImprovements in Negative-Outline-Indicating Devices, of which thefollowing is a description, reference being had to the accompanyingdrawings, which are a part of this specification. a

This invention relates to improvements in negative outline indicatingdevices.

In the photo-engravingart it is the usual custom to outline on thenegative used rectangular lines to indicate the dimensions of thephoto-engraving to be made fromthe negative, and also to properlyposition the illustration medially within the lines marked on thenegative. In outlining, the negative is usually placed on a rectangularboard and a T-square is placed over the negative at approximately theplace to properly po sition the illustration, and a rule is used tomeasure the length of the line desired and marks are then made toindicate the ends of the line. The line is then marked or cut on thenegative along the edge of the T- square and the same measuring andindicating and marking is followed with reference to the other lines tocomplete the rectangular inclosing lines around the illustration. Asonly one line, is indicated at a time it is 0fttimes found that when theoutliningis completed the illustration is not properly positioned withinthe rectangular outline and the work has to be done over again.

It is one of the objects of this invention to overcome the beforementioned objectionable features and to provide a negative outlineindicating device which may be adjusted to indicate rectangular outlinesof various dimensions and which will permit the illustration of thenegative to be properly centered with relation to the outline before theoutline is marked on the negative. 7

A further. object of the invention is to provide a negative outlineindicating device which is easily adjusted, is strong and durable, andwhich may be manufactured for a minimum amount.

With the above and other objects in View, the invention consists oftheimproved negative outline indicating device and its parts andcombinations, as set forth in the claims,

and all equivalents thereof.

In the accompanying drawing in which the same reference charactersindicate the same, parts in all of the views: Figure 1 1s a top view ofthe improved negative outline indicating device; Fig. 2 is a sectionalview thereoftaken on line 2-2 of Fig. 1; Fig. 3 is a sectional view ofthe device taken on line 33 of Fig. 1; andFig. a is a detail view of oneof the'slide members.

Referring to the drawing the numeral 8 indicates the frame or boardwhich is of rectangular shape and has a rectangular opening 9 coveredwith a transparent glass 10. A border 11, of yielding material,surrounds the glass and both glass and the material are set into theboard so that their upper surfaces will be approximately flush with theupper surface of the board. The lower side edge portions 'of-the boardare provided with depending reinforcing flange strips 12 to provide aspace 13, beneath the board proper, to accommodate movable and otherparts of the device. A bottom board 1 1 extends beneath the boardopening 9 and covers said opening, with the exception of two side edgesthereof, to form elongated slots 15 and 16 which extend at right angleswith relation toeach other. The edge portions of the bottom boardadjoining the elongated slots are provided with dimension scales 17 and18 divided to indicate the inches and fractions thereof.

The board is provided with elongated slots 19 and 20 extending in linesparallel to the slots formed in part by the edges of the bottom board,and upstanding fingers 21 and 22 extend into these slots 19 and 20 andare movable longitudinally therein.

The fingers form part of the tubular slidable members 23 and 2 1 whichare slidably mounted on the squared guide rods 25 and 26. These guiderods are positioned beneath the slots 19 and 20 and extendlongitudinally with relation thereto and are fastened to the board atopposite ends by screws 25.

The portions of the fingers 21 and 22 immediately above the slidablemembers are enlarged to accommodate the ends of indicatorrods 26 and 27which extend through openings 28 provided therefor. Screws 29, threadedinto the enlargements and impinging against the indicator rods, serve tofasten the said rods firmly to the slidable members. The indicator rodsare bent at an angle as at 30 to pass through the elongated slots 15 and16 and to clear the upper surface of the bottom board 14 and the lowerThese rods extend approximately across the opening of the board and atright angles with relation to each other and-are clearly discerniblethrough the glass and the negative3l resting on the glass. T square 32is provided andis adapted to be used as a straight edge inmarkingtlie'outline on t -he members discernible through the negativenegative.

In use the :shdable members are moved along the guide rods until theindicator rods are positioned above the-scale at the desired points toindicate the size of ltheoutline in inches or fractions thereof; The-negative is now placed on top of the glass and moved to a medialposition With relation to the lines indicated by the 'rods'and the edgesof the scale and visible through the negative, and when the illustrationis properly rpositioned the recta ugiilar outline is marked on thenegative over the indicated lines, *the T square and a pencil or knifebeing used for that purpose. H

"F tom the foregoing description it will be seen that the negativeoutline indicating device is ot very simple'construction and is easilyadjusted to indicate a rectangular outline of various dimensions and 'isWell adapted for the :purpose :desired.
